Drugs used before visiting

Chloroquine (weekly) remains an appropriate agent for prophylaxis in regions without resistant P falciparum as does mefloquine (weekly) for regions with P falciparum resistance to chloroquine. In areas with multidrug-resistant malaria, the choice is either doxycycline or Malarone (atovaquone plus proguanil); both drugs must be taken daily. Primaquine (daily for 14 d) is recommended for terminal prophylaxis of P vivax and P ovale infections and is an alternative in primary prevention.
